Obstructive sleep apnea (OSA) is highly prevalent in commercial vehicle operators (CMVOs). This study aimed to evaluate the poor sleep quality, daytime sleepiness, and the prevalence of self-reported OSA in CMVOs. SUBJECTS AND METHOD: We performed a retrospective review of the medical records of patients who visited a single institution with sleep problems from 2011 January to 2016 December. Among the patients, a total of 38 CMVOs was analyzed. Clinical information, questionnaires about sleep quality (Pittsburg sleep questionnaire, PSQI), excessive daytime sleepiness (Epworth sleepiness scale, ESS) and risk factors for OSA (STOP-Bang) were analyzed. The frequency of motor vehicle accidents and near accidents was assessed, and polysomnography (PSG) was used for OSA diagnosis purposes.
The mean age of the study population was 45.3±11.8 years. The average score of PSQI, ESS, and STOP-Bang were 6.75±4.22, 10.79±7.12, and 4.62±3.34, respectively. A significant association between near accidents and high-risk group of OSA was observed [odds ratio (OR)=2.73, 95% confidence interval (CI)=1.08-4.48]. Subjects with poor sleep quality showed significantly increased risk of near accidents (OR=2.34, 95% CI=1.01-3.56). Receiver operating characteristic curves of STOP-Bang questionnaire using apnea-hypopnea index (cut-off value=5) indicates that suspected OSA group predicted by STOP-Bang score was significantly correlated with OSA severity (area under curve=0.72, sensitivity 77.1%, specificity 59.4%).
Administration of STOP-Bang questionnaire before a PSG can identify high-risk subjects, supporting its further use in OSA screening of CMVOs.
